4 Claims. I

This invention relates to hoisting apparatus and more particularly to hoisting apparatus in which the load being hoisted when it reaches Ia desired hoisted position may be rotated through an angle of st and moved away from the original hoisting axis before being lowered to rest upon suitable supports.

The hoisting apparatus of the present invention is suitable for many uses and has particular application for use in the hoisting and locating of tobacco hangers in tobacco drying barns. The invention will be hereinafter described with particular reference to this use but it is to be understood that the invention is not so limited.

Heretofore various hoisting apparatus have been suggested for hoisting tobacco hangers, among other uses, but none of these have pro.- vided means for rotating the hanger withits load. of tobacco leaves through a 90 angle to place the same at right angles to th direction of the supporting rafters of a barn and at the same time to move he tobacco hanger and its load away from the original axis of hoist so that when the hanger i lowered it will be appropriately placed and spaced on the supporting rafters.

It is accordingly an object of the present invention to provide novel hoisting apparatus by which th load being hoisted may be rotated through an angle of 90 and at the same time displaced laterally from the original axis of hoist to appropriately position the load upon supports when the load is lowered.

Another object is to provide such hoisting apparatus in which the load to be hoisted may be elevated between series of supporting beams and in a desired position, rotated through an angle Oi 90 and displaced laterally so the load will rest upon desired supporting beams when lowered.

Another object is to provide such hoisting apparatus which is of simple construction, easy to manufacture, and easily handled by one man.

Another object is to provide such novel hoisting apparatus which is light weight and easily positioned and moved during the operation of filling a such as a tobacco drying barn,

Other and further objects of the present invention will appear from the following description.

The hoisting apparatus of the present invention is capable of various mechanical embodiqments one or" which is shown in the accompanying drawings and is described hereinafter for our' os s of illustrat ng the same. This illustrae embodiment of the present invention should ":n no be construed as defining or limiting the same and reference should be had to the 3P? 2 pended claims to determine the scope of this invention.

In the accompanying drawings, in which like reference characters indicate like parts, Fig. 1 is a view of an illustrative embodiment of the hoisting apparatus of the present invention showing its use for hoisting tobacco hangers with the hanger arranged lengthwise so as to pass between supporting beams in a tobacco barn;

Fig. 2 is a view of the embodiment of Fig. 1 showing the apparatus of the present invention with a tobacco hanger inhoisted position and partially rotated about the hoisting axis and partially displaced laterally therefrom and rotating toward its position of rest across supporting beams in a tobacco barn; and

Fig. 3 is a view of the apparatus of Fig. 1 with the tobacco hanger rotated through an angle of 90 from the position shown in Fig. 1, laterally displaced from the hoisting axis of Fig. 1 and positioned for lowering onto the supporting beams of the barn.

Referring now to the several figures, suitable supporting beams for tobacco hangers such as are foundin a tobacco barn are generally indicated at Ill. These beams H) are arranged in parallel relationship and are laterally and vertically spaced in conventional manner as is well known to theart. In the embodiment of the hoisting apparatus of the present invention as disclosed in these figures H represents a cross beam rounded at its ends as at :2 and I3 and of suitable length to rest upon adjacent parallel beams [0. The ends l2 and is are rounded so that beam H is free to rotate upon the support.- ing beams It. A cross member !4 is secured midway between ends it and I3 and supports a suitable pulley it at one end thereof. A hoisting line it passes through pulley l5 and is provided with a hoisting frame ill at one end. The other end of rope it passes through eye it secured to frame ll. Frame II is provided with turned parallel ends 19 and 20 to receive a suitable tobacco hanger 2 I.

An arm 22 is mounted for universal motion at 23 upon beam I I. A second arm is universally connected at 25 to the free end of arm 2'2. The other end of arm 24 is secured to a circular drum 25. Drum 2-8 rotates about a pivot 21 which passes through a fork 28, which embraces arm 24, and fork 28 terminates in stem. 253 which is mounted for rotation in bracket 3!} which is secured by screws 3| to a side of beam H. A bar 32 having a ring end 33 is loosely mounted 011 $3? 4 which is secured to the end of cross member I4 opposite the pulley IS. A second link 35 is loosely connected to link 32 at 35 and in turn is loosely connected at 31 to a rod 38 carrying a stop 39. A guide 49' receives rod as and is secured to arm 24. A guide rope fill is connected at 4| to rod 38. An extensible spring loaded link 42 is secured to frame I! and terminates in an eye d3 embracing guide rope is. A connecting rod dd may be rigidly secured to arm 22 and loosely connected to the flexible connection 36.

Suitable resilient means such as the spring 45 embraces the outer circumference of drum 26 and is secured at one end thereto as at 46 and is secured at its other end as at 4? to beam I I.

In using the embodiment of the present invention as described and particularly when using it for the hoisting and placing of tobacco hangers the beam II is suitably placed upon supporting rafters It as shown in Fig. 1 and a hanger 25 supporting tobacco leaves in known manner is placed upon ends as and 20 of frame Iil. Hoisting rope I6 is then hauled to raised frame I! and hanger 2d, eye I8 riding over rope It to prevent swinging of hanger I! and to keep the long axis of hanger 2i parallel to the rafters Ill. When frame I! has reached its elevated position adjacent pulley l guide rope 4!} is hauled. Hauling on guide rope 4i! starts frame ll rotating through the agency of extensible connector 42 and at the same time engages stop 38 against guide 43 and rotates arms 22 and 24 about their respective pivots 23 and 21, the motion of arm 24 tensioning spring 45. An intermediate position of the hoisting apparatus of the present invention with frame I! and tobacco hanger 2! partially rotated about the axis of hoisting rope I6 is shown in Fig. 2. Further hauling upon guide rope 48 rotates arms 22 and 24 to their extreme positions at which links 32 and 35 prevent further motion of arms 22 and 2c and thereafter further hauling on rope 49 rotates cross member I4 into a horizontal position displacing frame iI lateral- 1y away from the original hauling axis and completes a 90 rotation of frame I! and hanger 2|. Thereafter hauling rope It can be slacked away and hanger 2% is lowered into position upon the supporting rafters ID. This last position of the hoisting apparatus and hanger BI is shown in Fig. 3 with the tobacco hanger iii in lowered position shown by arrows and dotted lines.

The extensible feature of connector 133 permits lateral displacement of frame I! and hanger 2| while at the same time holding and swinging them through the desired ninety degrees of rotation.

After tobacco hanger 2| is in place upon the rafters IO hoisting rope is is further slacked oif until frame I! disengages hanger 2i. Thereafter guide rope 40 is slacked off allowing cross member M to rotate beam I I so that pulley It moves to its lowest position as shown in Fig. 1. At the same time spring 45 is rotating drum 2e and arm 24 toward the position shown in Fig. 1 carrying arm 22 and associated linkage with it. Extensible member 52 is contracted to its initial position and frame I! swings through a 90 angle to a position in which its plane is parallel to the long axes of the rafters Iii. Frame ll may now pass downwardly through the parallel rafters Ill without engaging them and hoisting rope I5 is further slacked ofi for this purpose.

It should be particularly noted that when the hoisting apparatus of the present invention is in the position shown in Fig. 1 all of its elements are in substantially the same plane so that the hoisting apparatus may be easily hoisted upwardly between the parallel rafters I0 and can be moved about within the restricted openings found in conventional tobacco barns without difficulty. 'Such would not be the case if the arms 22 and 24 with associated linkages were aflixed in the position shown in Fig. 3 although if so fixed in position the operation of the apparatus would be substantially as described above. The motion provided arms 22 and 24 by the guide rope 40' is a desirable feature of the present invention in View of the compactness thereby provided for the apparatus. However it is within the scope of the present invention to fix the arms 22 and 24 in somewhat the position shown in Fig. 3 although thereby losing the advantages of compactness.

It should now be apparent to those skilled in the art that changes in or modifications to the above described illustrative embodiment of the present invention can be made without departing from the inventive concept thereof even though such departures might reduce the compactness of the apparatus or its ease of operation in restricted spaces. For example, instead of employing arms 22 and 24 with associated linkages the guide rope 40 could be connected to an arm rigid with cross member I 4 and extending at right angles thereto adjacent the end of arm [4 and opposite the pulley I5. Such a structure would, however, lose the compactness of the described embodiment of the present apparatus and would limit the utility of the same in and about restricted spaces. In view of the changes possible to the described structure of the present invention reference should be had to the appended claims to determine the scope of the same.
